Is a Firm or Medium Mattress Better For Kids

April 23, 2024   By JM Carpiso

Choosing the right mattress for your child can be a difficult task.

There are many factors to consider, from size and material to price and brand.

Yet, one aspect that often leaves parents confused is the firmness of the mattress.

Should you opt for a firm mattress or a medium one for your child?

In this article, we will discuss which is the better choice for your kid.

We will discuss the pros and cons of firm and medium mattresses for kids, helping you make an informed decision.

Understanding Mattress Firmness

Mattress firmness refers to how hard or soft a mattress feels when you lie on it.

It’s measured on a scale from 1 to 10, with 1 being extremely soft and 10 being extremely hard. A firm mattress typically falls between 7 and 10 on this scale, while a medium mattress ranges from 4 to 6.

The Importance of Mattress Firmness for Children

The firmness of a child’s mattress can significantly impact their sleep quality and spinal health. A mattress that is too soft may not provide adequate support, leading to poor posture and discomfort. On the other hand, a mattress that is too firm can cause force on your child’s pressure points, disrupting sleep and potentially causing pain.

Children are in a crucial stage of growth and development. Their bodies constantly change, and their mattress needs to accommodate these changes. A mattress that provides the right level of firmness can support a child’s developing spine and promote healthy growth.

Moreover, the right mattress firmness can also influence a child’s sleep patterns and behaviours. A comfortable and supportive mattress can help children fall asleep faster, stay asleep longer, and wake up feeling refreshed. This can have a positive impact on their mood, behaviour, and overall well-being.

Firm Mattress: Pros and Cons for Kids

A firm mattress can offer several benefits for children. One of the main advantages is the level of support it provides. A firm mattress can help maintain proper spinal alignment, which is crucial for growing children. It can also prevent them from sinking too deeply into the mattress, leading to discomfort and poor sleep quality.

However, a firm mattress may not be the best choice for all children. Some kids may find a firm mattress uncomfortable, especially if they sleep on their side or stomach. A firm mattress can create pressure points in these positions, leading to discomfort and disrupted sleep.

Here are some pros and cons to consider:


  • Provides excellent support
  • Helps maintain proper spinal alignment
  • Prevents sinking into the mattress


  • May be uncomfortable for side or stomach sleepers
  • Can create pressure points
  • May be too hard for lighter children

Medium Mattress: Pros and Cons for Kids

A medium mattress, on the other hand, strikes a balance between firmness and softness. This type of mattress can provide a comfortable sleep surface for children, while still offering adequate support. A medium mattress can conform to a child’s body shape, providing pressure relief and reducing the risk of discomfort or pain.

However, a medium mattress may not provide enough support for heavier children or those who sleep on their back. It may also sag over time, which can lead to poor spinal alignment and discomfort. Additionally, some children may simply prefer a firmer or softer mattress, depending on their personal comfort preferences.

Here are some pros and cons to consider:


  • Balances comfort and support
  • Conforms to body shape for pressure relief
  • Suitable for most sleep positions


  • May not provide enough support for heavier children
  • Can sag over time
  • May not suit children who prefer a firmer or softer mattress

Firm vs Medium: Comparing Support and Comfort

When comparing a firm and medium mattress, it’s important to consider both support and comfort. A firm mattress offers superior support, which can be beneficial for their back and the development of their spine as well as growth. However, it may not provide the same comfort level as a medium mattress, especially for side sleepers or children who prefer a softer sleep surface.

On the other hand, a medium mattress offers a balance of comfort and support. It can conform to a child’s body shape, providing pressure relief. But, it may not provide enough support for heavier children or those who sleep on their back.

Considering Your Child’s Sleep Position and Weight

Your child’s sleep position and weight also play a crucial role in determining the right mattress firmness. For instance, back and stomach sleepers often require a firmer mattress to maintain proper spinal alignment. On the other hand, side sleepers might benefit from a medium mattress that can cushion their shoulders and hips.

Weight is another important factor. Heavier children may sink too deeply into a medium mattress, leading to poor spinal alignment. A firm mattress can provide the necessary support. Conversely, lighter children might find a firm mattress too hard and uncomfortable, making a medium mattress a better choice.

Health Considerations and Special Needs

When choosing a mattress for your child, it’s essential to consider any health issues or special needs they may have. For instance, children with certain medical conditions, such as scoliosis or other spinal issues, may require a specific type of mattress for optimal comfort and support.

Additionally, children with allergies or sensitivities might benefit from hypoallergenic mattresses. These are often made with natural materials that resist dust mites and mould. Always consult with a healthcare provider to understand the best mattress firmness and type for your child’s specific needs.

How to Test and Assess Your Child’s Mattress Preferences

Understanding your child’s mattress preferences can be a bit tricky. However, observing their sleep patterns and asking about their comfort can provide valuable insights. Notice if they seem restless, frequently change positions, or complain about discomfort. These could be signs that their current mattress isn’t meeting their needs.

Consider a sleep trial if available. Many mattress companies offer trial periods where you can return the mattress if it doesn’t suit your child. This can be a great way to test different firmness levels and find the one that your child prefers.

Conclusion: Making the Right Choice for Your Child

Choosing the right mattress for your child is a crucial decision that can impact their sleep quality and overall health. Whether a firm or medium mattress is better depends on various factors, including your child’s weight, sleep position, and personal comfort preferences.

Remember, there’s no one-size-fits-all answer. It’s about finding the right balance between comfort and support that suits your child’s unique needs. Don’t hesitate to consult with a paediatrician or a sleep specialist if you have specific concerns. After all, a good night’s sleep is fundamental to your child’s growth and development.
